I’ve finished with implementation of the sea quests backend and now you may become a pirate! The pirate island is unlocked after you complete the coast.
Yet there is nothing you can do as a pirate, but I’ll add something soon: the shipyard, where you’ll be able to upgrade your ship, and some more sea quests!
Note, that swimming on your boat, your potions will not be available. I’ll add some special ship abilities later, such as ship repair during the quest (like health potions). Just now there is only one special ability available: lower the sails (the «L» hotkey), which will stop your boat from moving forward.
P.S. It seems that your saves from previous builds would not work, so you’d better start from the beginning to check the pirate island 🙁
